There’s loads of imagination and energy (if not much taste) in this hyperventilated Spielberg-produced animated feature (1993)—probably too much for the 72-minute running time, inasmuch as characters, settings, and plot situations are sideswiped rather than introduced or developed. (It’s probably a market strategy: selling toys and other products derived from the movie is probably easier if kids feel they’re not getting enough the first time around.) Some prehistoric beasts are visited by a flying saucer, fed “brain grain,” and transported to contemporary New York City, where they’re befriended by a wily street kid and a lonely debutante. But they’re waylaid by an evil circus master who feeds them “brain drain,” and they become horrific beasts again. Among the recognizable voices are those of Walter Cronkite, John Goodman, Jay Leno, Martin Short, and Julia Child. Adapted by John Patrick Shanley from a book by Hudson Talbott and directed by several hands.
